WebJan 24, 2007 · SPAD performance simultaneously exhibits a dark count rate of 10 kHz at a detection efficiency of 20% with timing jitter of 100 ps at 200 K, and with appropriate performance tradeoffs, we demonstrate a 200 K dark count rate as low as 3 kHz, a detection efficiency as high as 45%, and a timing jitter as low as 30 ps.
WebJan 3, 2024 · When extremely small optical powers need to be detected, we need to consider dark count. Thus, dark count will limit single photon detection capability. The following is the data extracted: Detection rate ch.2 (counts/s): 124. Detection rate ch.4 (counts/s): 612. Coincidence rate (pairs/s): 0. Delay (ns): 0. WebNov 22, 2016 · The dark count rate (DCR) is a key parameter of single-photon detectors.
